FLUE CAP.

Application filed November T 0 all whom it may concern.

Be it known that I, HENRY J. VVILDHAGEN, a citizen of the United States, residing at Palatine, in the county of Cook and State of Illinois, have invented new and useful Tm provements in Flue Caps, of which the following is a specification. V

This invention relates to flue caps particnlarly designed for forming closures for the stove pipe receiving branch openings of fines, and an object of the invention is to provide a. cap or closure which; will tightly seal the flue branch opening and prevent sifting of soot, fire, or the like through the opening and also to provide a cap which comprises a o inner closing plate forming an abutment against which the soot may accumulateand which will also serve to form a closure for the branch flue opening in case wind displaces the outer closing plate or it becomes displaced for any reason whatsoever, thereby preventing the sifting of soot or other foreign material into the room.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawing wherein:

Fig. 1 is a vertical section through a flue showing the cap in place Fig. 2 is a section through the cap.

Fig. 3 is an elevation of the outer end of the cap.

Fig. 4 is an end elevation of the inner end of the cap.

Referring more particularly to the drawing, the improved flue cap comprises a spacing sleeve 1 through which a bolt 2 extends. The bolt 2 also extends through the outer closure plate 3, which is held in firm abutment against the intermediate portion of the confining spring members 4: by the annular flange 5 formed upon the bolt 2. A nut 6 is threaded on the bolt 2 and clamps'against the inner plate 7, forcing this plate against a spacing washer 8 which is in turn forced against the end of the sleeve 1. The clamping of the nut 6 against the plate 7 also tends to clamp the flange 5 against the plate 3. The bolt 2 has a head 10 formed thereon to facilitate the removal of the cap from the flue branch A. I

The spring members 4 are preferably formed of continuous piece of metal having its intermediate portion mounted upon the b01t2 and disp sed between the sleeve and 3, 1922. Serial No. 598,842.

the plate 0 The as illustrated in Fig 2.

ends of the strip are curved toward each noted from the illustration in Fig. 1 that the. ends of the springs at are maintained in spaced relation with the sleeve 1 so that they will retain their full resiliency for engagement with the inner surfaces of the fine.

It is, of course, to be. understood that the invention may be constructed in other manners and the parts associated in different re lations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is I"? .l. A flue cap comprising a bolt, a spacing sleeve on said bolt, spring members formed of a continuous strip of metal mounted at its intermediate portion upon said bolt, said strip having its' ends curved toward each other, the intermediate portion of the strip engaging one end of the sleeve, a plate abutting said strip, an inner plate at the inner end of said sleeve, and a nut threaded on said bolt for clamping the plates in position.

2. A flue cap comprising a bolt, a spacing sleeve on said bolt, springmeinbers formed of a continuous strip of material mounted at its intermediate portion upon the bolt and engaging one end of the sleeve. the ends of said strip being arcuately curved inwardly towardeach other to provide substantially convex curved portions on each side of the spacing sleeve for yieldable engagement with a flue, a plate abutting the intermediate portion-of the strip, a flange on one end i of the bolt engaging said plate, an inner plate at the other end of said sleeve of a substantial size tofit snugly within the flue, and a nut threaded on the belt for clamping said plates in position. 7

In testimony whereof I aflix my signature.
